Specification of Letters Patent.

Patented June 23, 1908.

Application filed October 31, 1906. Serial No. 841,437.`

\ which wi lock with the parts to be coupled,

drawings.

so that their fixed relation, when clamped, is assured.

In the embodiment of the invention disclosed in the accompanying drawings, the structure is shown applied to a wire cable, and while peculiarly applicable to the same, is nevertheless useful in other analogous relations.

i In the drawings z-Figure 1 is a side elevation, showing the portions of'a cable held by the improved means.

Fig. 2- is a cross sectional view therethrough. Fig. 3 is a longitudinal sectional view. Fig. 4 is a' detail perspective view of the base plate. Fig. 5 is a similar view of the intermediate clamping block. i

Similar reference numerals designate corresponding parts in all the figures of the In the Yembodiment disclosed, relatively adjustable outer clamping membersaie employed, together with an intermediate .mem-

er of soft metal that is disposed between the outer members, and is arranged to be laced between the articles to be coupled. T us in the present embodiment, one of theouter members consists of a base plate 6, havinga longitudinally and centrally disposed rib 7 on one side, which rib is provided with a longitudinal seat 8 .that is tapered or substantially tl-shaped in cross section and is preferably roughened as shown in Fig. 4. Sets of openings 9 are formed in the plate on o posite sides of the rib. Associated with t ie said plate arel other. clamping ,members in the orm of U-shaped yokes 10, having side arms 11 that ass 'through the openings 9, the free terminaie of the arms being' threaded, as illustrated at 12. Nuts 13 are screwed upon the threaded ends, and bear against the outer side 'of the plate, thus vserving tok draw the yokes through the plate,v` as will be understood. While two yokes are shown in the present embodiment, it will be apparent that after which the nuts 13 are screwed .one or more may be employed as desired. The intermediate member consists of a block 14, formed of lead or other soft material, the block being arranged to fit between the side arms of the yokes, and having longitudinally recessed seats 15 in its opposite sides, the

seats being tapered or V-shaped in cross section.

In usin the device, the soft metal block 14 is placed etween the articles to be coupled, as for instance, the sections of a cable. The yokes embrace said articles or sections, and are passed through the openings in the plate, home. The result is that the intermediate block or member will be securely clamped between the articles or sections, and being of soft metal, will conform substantially to the engagin faces thereof, entering the interstices, and t us interlocking with both sections. Consequently a peculiarly effective cou ling is provided, which will efficiently hol the arts against relative movement, said cou ing beingreadilyattachable to and detac able from the parts thus connected.

It will be lnoted that the block 14 is entirely separate from the okes, and is nari rower than the distance etween the arms thereof, so that it may be readily slipped into place. In like manner, the rib 7 is narrower than the distance between the oke arms, these arts being furthermore ofy less width than tlie diameter of the cable so that their edges and the sharp corners will effectively engage the cable and prevent its slip ing.

From the foregoing, it is thought t at the construction, operation,- and many advan- -tages of the herein .described invention will be apparent to those skilled in the art, without urther description, vand it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to Within thescope of the appended claims without departing from the spirit or sacrificing any of theadvantages of the invention.

- Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cou' lingof the character described, they combination with a base late, of a yoke having spaced arms passing t roulgh the base plate, means for drawing theyo e Athrough said plate, and an intermediate member of softer material than the base plate and yoke and of less width than the distance between the arms of the latter, said member being independent of the arms and being detachably iitted between the same, being furthermore provided in its opposite faces with seats for the reception of cable sections placed in the yoke, said seats having-angularly disposed aces.

2. In a coupling of the character described, the combination with a base plate having spbaced sets of openings therethrough, and a r1 projecting from 011e face and extending between the openings of the different sets and of less width than the distance between them, said rib havin a cable receiving seat composed of an ular y disposed ilat faces, 0f a plurality of yo es, each having spaced arms passing through the openings of one of the iitted between the arms and being rovided in its op osite faces with seat-s for t e reception of t e cable section, said seats having an ularly disposed faces. v

n testimony, that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
